[PATCH] log more info for directory entry change events
When an audit event involves changes to a directory entry, include
a PATH record for the directory itself. A few other notable changes:
- fixed audit_inode_child() hooks in fsnotify_move()
- removed unused flags arg from audit_inode()
- added audit log routines for logging a portion of a string
Here's some sample output.
